  30. Function of sensory neurons?
    (Afferent)
    - Neural impulse is sent to central nervous system from receptor or sensory organ.
  31. Function of motor neuron?
    (Efferent)
    - Neural impulse is set to receptor or enory orga from central nervous system.
  32. Function of interneuron
    - Nerve cell found throughout the entire CNS that link between sensory neurons & motor neurons.
